How can you solve factorial expressions?

Answer 1

To solve factorial expressions, first understand the definition of a factorial: for any positive integer ( n ), ( n! ) (n factorial) is the product of all positive integers from 1 to ( n ). For example, ( 5! = 5 \times 4 \times 3 \times 2 \times 1 = 120 ). You can simplify expressions by canceling common factorial terms, using properties like ( n! = n \times (n-1)! ), and applying factorial identities. For larger calculations, consider using a calculator or software to handle the computations efficiently.
